Well made koummya

[corrado26]

I agree with the two smaller pieces probably made more recently, but I cannot agree with the big one having the same age. This is a very massivly made piece with a weight of nearly 500g, made of bronce (no brass) and iron sheet with an average thickness of more than 1,00 mm.
As Kubur says, " if for example the grooves on a blade were not chiseled by hand but machined with a rotating tool" this would be a sign of modern workmanship. That's ok, but with a normal magnifier one can see the traces of the knife that has cut the grooves in this blade.
Some more pictures - two Fotos in comparison with an old koummya of normal length - may help to clear some things.
